R chiral
WebSince the cis isomer has two centers of chirality (asymmetric carbons) and is optically inactive, it is a meso-compound. The corresponding trans isomers also exist as rapidly interconverting chiral conformations. The diequatorial conformer predominates in each case, the (R,R) conformations being mirror images of the (S,S) conformations WebChiral model. Soliton scattering process for two solitons in the integrable chiral model. The plot shows the energy density of the system, and the maxima represent the solitons. [1] [2] In nuclear physics, the chiral model, introduced by Feza Gürsey in 1960, is a phenomenological model describing effective interactions of mesons in the chiral ...

Chirality (from the Greek word cheir, meaning “ hand ”) is the geometric property displayed by any object that is non-superimposable on its mirror image. The main structural feature responsible for chirality is the presence of dissymmetry; as it has no plane of symmetry (as previously explained).
